Network Policies Configuration

Network policies allow QuTS hero users to manage data traffic by implementing data reliability policies on the network adapters of the device.

Configuring Forward Error Correction (FEC) Settings

Forward Error Correction (FEC) is a digital signal processing technique to recover lost packets on a link by sending extra parity packets. Enabling FEC enhances data reliability by introduces redundant data or error correcting data before the system stores or transmits data.

  1. Go to Control Panel > Network & File Services > Network & Virtual Switch.

    The Network & Virtual Switch window opens.

  2. Go to Network > Interfaces.
  3. Identify the adapter that you want to configure, then click > Configure.

    The Configure window opens.

  4. Click FEC Settings.
  5. Click Enable forward error correction (FEC).
  6. Select an FEC mode.

    Description

    Auto-negotiation

    The device automatically selects the best FEC mode.

    BASE-R FEC

    BASE-R FEC (also known as Fire Code FEC or IEEE 802.3 Clause 74) offers simple, low latency (less than 100 nanoseconds) protection against bursty errors. This mode offers a weaker error correction but with lower latency.

    RS-FEC

    RS-FEC (also known as Reed Solomon FEC or IEEE 802.3 Clause 91) offers better error protection but adds latency (approximately 250 nanoseconds).

    Important:

    The same FEC mode should be selected on both ends of the network link.

  7. Click Apply.

Network & Virtual Switch applies the FEC settings.
